One biologist claimed that the bear population was proportionally related to the number of years after they were reintroduced into the wild. Based on the information in the table, would you agree? Explain your answer
(1 point)
The bear population is not proportionally related to the number of years because the ratio in the last row is not equal to the
ratios in the first two rows
The bear population is proportionally related to the number of years because the ratios are equivalent
The bear population is not proportionally related to the number of years because the ratios are equivalent
The bear population is proportionally related to the number of years because the ratios are not equivalent
The correct answer is:
The bear population is not proportionally related to the number of years because the ratio in the last row is not equal to the ratios in the first two rows.
The bear population is not proportionally related to the number of years because the ratios in the last row are not equal to the ratios in the first two rows.
To determine whether the bear population is proportionally related to the number of years after they were reintroduced into the wild, we need to examine the ratios in the table.
Let's calculate the ratios for each consecutive pair of years:
Ratio between year 6 and year 1: 6/1 = 6
Ratio between year 20 and year 6: 20/6 = 3.33 (approximately)
Ratio between year 120 and year 20: 120/20 = 6
Ratio between year 240 and year 120: 240/120 = 2
Ratio between year 60 and year 240: 60/240 = 0.25
By comparing the ratios, we can see that they are not equal. The first two ratios are 6 and 3.33, respectively, which are not equivalent. Therefore, we can conclude that the bear population is not proportionally related to the number of years based on this table.
The correct answer is: The bear population is not proportionally related to the number of years because the ratios in the last row are not equal to the ratios in the first two rows.
